120hz vs 144hz on an OLED TV

So, buying a TV for the PS5 Pro.

I learned here that having a higher Hz monitor does help with input lag and smoothness, because the scannout rate when using VRR benefits from the monitor's highest Hz. My question is, how big is the difference is it between 120Hz VRR to 144Hz VRR when content runs at 60-120FPS (PS5 Pro rates)? Because I eyed the S90D/C4 (144hz), but can get the S85D/B4 (120hz) for about $1K less.

Thanks.

There should be zero difference in that scenario; PS5 Pro doesn't support 144Hz output, so it won't be able to take advantage of the extra 24Hz for 120 FPS games anyway; the TV will just fall back to 120Hz.

That, and while I can't speak to the S90D, the 144Hz mode on the C4 is technically an overclock, which I haven't found to be glitch free, at least for PC use. I don't bother with it, and use 120Hz instead, currently.

Wait, the PS5 Pro doesn't support keeping the scannout frequency of the monitor at 144hz?

P.S - how do you find OLED/QD-OLED monitors compared to good Mini QLEDS like those by Hisense / TCL ? Night and day difference? Because the bigger size (per $), the aid in daylight viewing, and the lack of need to babysit an OLED are tempting.

The scanout speed is tied to the physical refresh rate, so if the PS5 Pro doesn't support a physical 144Hz refresh rate output (it doesn't), and only supports a 120Hz refresh rate, then the TV will be in 120Hz mode and you'll get a 120Hz scanout.

OLED has true black and virtually no ghosting. The same can't be said for QLED.

1. So when you're gaming on a 144Hz monitor, with a game that runs on 50FPS, on the PS5 Pro, you're basically using a 120Hz VRR, having a scannout of 120Hz while the actual refresh rate is 60Hz due to the FPS?

2. As for the OLED, kinda worried it won't be bright enough during daylight, when the living room gets a healthy amount of sunlight.

Yes.

Close the curtains :P

On a more serious note, you should look up the brightness of your current display on rtings.com at a specific brightness setting, and then try to match the maximum fullscreen brightness of the OLED (as reported by rtings.com.) Then you can judge for yourself if it's gonna be bright enough or not.

Curtains not nearly enough to block it :)

Currently using a very basic 70" UP7750 (LG). I don't quite understand what the numbers on Rtings mean and what I should look for, but my current TV is bright enough I think, just highly reflective. Here's a picture of it, at 100% brightness, on 12:30PM:

Where I live, I could get these brand new, with a 3 year warranty:

75" TCL QM8B - $1,636
77" Samsung S85D - $1,938
77" LG B4 - $2,187
77" Samsung S90D - $2,843

There's also an outlet that sells the next models' leftovers, all with a 1 year warranty. The LG monitors were all used to showcase the monitors in the distributor's gallery shop. Warranty extendable to 4 years for $600. The Samsung models are all either leftovers (unused) or returned items from customers, with a 1 year warranty (un-extendable):

65" Samsung S95B - $1,000
65" LG C2 - $1,010
65" LG C3 - $1,092
65" Samsung S90C - $1,133
77" LG B3 - $1,640
77" Samsung S90C - $1,780
77" LG C3 - $1,916
77" LG G2 - $2,188
77" LG G3 - $2,461

Which one would you go for?

Use-cases are 75% night (PS5 or Netflix), and 25% day (cartoons, news, occasionally PS5 or Netflix)

Is the limitation from the GPU, or from the actual HDMI port as opposed to Display Port ?

It's more of a choice on Sony's part to not support 144Hz or higher output, and not as much a limitation, per say; 120Hz is a far more common refresh rate for TVs, and the PS5 is a console, not a PC, where higher than 120Hz monitors are much more prevalent. That, and most PS5 games can barely reach a true 120 FPS anyway, let alone 144.

But wouldn't supporting higher Hz help with the input lag (due to faster scannout speeds), even if FPS is double digits?
